Hello everyone,
I'm writing to announce a new Youtube channel from veteran teacher and BATMather Marc Roth, available
here, where he shares original teaching ideas. He has already released video on the harmonic mean, completing the square, and one of his MTC presentation topics, Bowling Pin Puzzles.
This is good stuff, so please check it out if you're so inclined; and consider subscribing and sharing out his work in order to support the community.
Take care all and I hope the fall is going as smoothly as it can.
Elysée
